Deploy One Rust Binary, Scale Forever

When you run swift-rust build --binary, the output is a single self-contained native executable containing the Rust Hyper HTTP server, your pre-rendered static assets, optimized route bundles, and the ISR cache engine.

Deploying a single binary transforms production operations:

1. Microsecond Cold Starts: Process startup takes ~4ms with a ~28MB idle RSS footprint—roughly 5x leaner than a standard Node.js server container. 2. Zero Runtime Drift: No node_modules directory in production, no missing native shared libraries, and no lockfile mismatches at deploy time. 3. Built-in Observability & Cache Control: Native /_swift-rust/revalidate endpoints with HMAC-SHA256 verification and OpenTelemetry-ready request tracing out of the box.
